Accessories & Customization
Electrolyte Supply: JLY-YF-B02 is available in research-grade quantities for lab-scale Lithium Metal Battery (LMB) validation.
Pouch Cell Prototypes: Specialized 4*50*78mm cells pre-filled with B02 electrolyte can be supplied for flight testing and data verification.
Testing Data: Full 0.2C/1C cycle life raw data and 3C rate discharge curves are available for institutional researchers upon verified request.
The JLY-YF-B02 electrolyte requires strict adherence to voltage, temperature, and discharge limits to prevent degradation and thermal hazards. Storage at 25°C and 100% state of charge is specified to minimize capacity fade with a retention factor of ≤0.06.
- Voltage Range Constraint: Operation must remain within 3.0 V to 4.3 V to avoid irreversible electrolyte decomposition or lithium plating.
- Temperature Operating Limits: Charge only between 0°C and 45°C and discharge between -20°C and 55°C to prevent thermal runaway and ensure stable cycling.
- Discharge Rate Limit: Continuous discharge must not exceed 3 C to avoid excessive heat generation and capacity loss.
- Storage Condition: Store at 25°C and 100% state of charge to maintain the specified storage performance with retention factor K ≤0.06.
- Anode Compatibility Requirement: Formulation is optimized for lithium metal and lithium alloy anodes; use with other anode chemistries is not validated.
What is the cycle life difference between the Standard and Upgraded versions of the JLY-YF-B02 electrolyte for lithium metal pouch cells?
The Upgraded Version (V.420) delivers ≥350 cycles at 0.2C charge/1C discharge, while the Standard Version (V.400) provides ≥250 cycles. Both maintain stable capacity retention, but the Upgraded version extends the plateau by 100 cycles, as specified in the performance comparison table.
What are the voltage and temperature operating limits for the JLY-YF-B02 electrolyte in lithium metal pouch cells?
The electrolyte operates within a voltage range of 3.0 V to 4.3 V, with a nominal voltage of 3.8 V. The charge temperature range is 0–45°C and the discharge range is -20–55°C, making it suitable for high-altitude UAV and aerospace applications where extreme thermal conditions occur.
What is the storage performance of the JLY-YF-B02 electrolyte and how does it affect shelf life?
The storage performance K is ≤0.06 at 25°C and 100% state of charge, indicating minimal capacity fade during storage. This parameter is critical for long-term deployment in HALE UAVs where extended idle periods occur, and is directly stated in the cell platform specifications.
The JLY-YF-B02 electrolyte in a 4*50*78mm pouch cell format delivers 400-420 Wh/kg specific energy with proprietary dendrite suppression, enabling >350 cycles at 0.2C/1C. The upgraded version offers 420 Wh/kg and 350 cycles, while the standard version provides 400 Wh/kg and 250 cycles. Operating constraints include a 0-45°C charge range and -20-55°C discharge range, with research-grade availability requiring institutional inquiry.
Positive
- Industry-leading energy density: Achieves up to 420 Wh/kg specific energy, providing a high energy-to-weight ratio optimized for long-range aerospace, UAV, and stratospheric platforms.
- Extended cycle life via dendrite suppression: Proprietary B02 electrolyte stabilizes the SEI layer and suppresses lithium dendrite growth, enabling >350 cycles at 0.2C charge/1C discharge with stable capacity retention.
Trade-offs
- Restricted temperature window: Charge operation is limited to 0-45°C and discharge to -20-55°C, which may constrain deployment in extreme thermal environments without active thermal management.
- Research-grade availability only: The electrolyte and pre-filled pouch cells are supplied in research-grade quantities, requiring institutional verification and direct inquiry for volume procurement, limiting immediate off-the-shelf access.
